AMASA O. VVOODBURY, OF PENNINGTON, TEXAS.

COTTON-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 403,403, dated May 14, 1889. Application filed January 2, 1889. Serial No. 295,222. (No model.)

To aZZ whmn it may concern-.-

Be it known that I, AMASA O. WooDBURY, a citizen of the United States of America, residing at Pennington, in the county of Trinity and State of Texas, have invented certain new and useful Improvements in Cotton-Choppers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in cotton-choppers, the same being capable of application to cultivators or double plows.

The invention comprises the details of construction, combination, and arrangement of parts, substantially .as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of my invention. Fig. 2 is a transverse sectional view on the line 00 00, Fig. 1. Fig. 3 is a detail.

Referring to the drawings, A designates a cultivator-frame having the ordinary shovels, a a.

B is a wheel having a series of arms, b, provided with U-shaped plates 1), designed to fit over or encompass the hills of cotton, and thereby protect the same and prevent the shovels from covering said hills. The ends of axle b of this wheel are secured in hollow tubes 0 0, attached to the sides of the frame, and upon said ends of the axle bear blocks D D, to which coil-springs (Z (Z are secured, the upper ends of said springs having screws (1 bearing thereon. By means of said screws and springs the axle can be held at the desired tension.

The rim of wheel B is provlded with a series of uniform offsets, E E, and curved or tapering side edges, against which are designed to bear rollers e e of hoe-bars F F.

The inner ends of these bars are secured to collars e on axle b and to their outer ends are attached hoe-blades e 6 designed to overlap each other at their contiguous ends. The inner portions of these hoe-bars F are made of spring metal, which holds the rollers firm against the inclined or tapering edges of the rim of wheel B.

In practice the cotton-fenders I) fit over the hills of cotton and the revolution of said wheel causes the operation of the hoes. As each fender encompasses a cotton-hill, the rollers e e pass over the offsets E E on wheel B, and the hoes immediately overlap, chopping between the hills of cotton.

The advantages of my invention will be apparent to those skilled in the art to which it appertains. The same is extremely simple and productive of good results.

I claim as my invention- 1. As an improvement in cottonchoppers, the wheel having the cotton-fenders, and the overlapping hoes having their bars operated by said wheel, substantially as set forth.

2. The combination, with the frame and axle, of the axle-supporting boxes or tubes 0, the blocks D, the springs d, and the adjusting-screws (1', whereby the axle-wheel is journaled in a yielding bearing, substantially as shown and described.

3. The combination, in a cotton-chopper, of the wheel having the series of arms, the V- shaped fenders secured thereto, the rim having offsets and tapering side edges, the hoebars having rollers, and overlapping hoes at their outer ends, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
